React Native Intern @paralleldots.combuilding @sarajod.com

Shubham Jangra

Software Engineer

I build React Native apps and full-stack products that hold up in production ~ not just in demos.

About

From scaling a mobile app to 10,000+ users at Suffai to shipping real-time features at ParallelDots, I build React Native and full-stack products that hold up in production ~ not just in demos.

I work across TypeScript, React Native, and Expo on the frontend, with Node.js, PostgreSQL, and MongoDB on the backend ~ owning mobile UI, APIs, WebSocket systems, OTA releases, and the messy parts in between.

At Tekora Labs, I shipped a multi-role society management platform across 3 production apps ~ finance, subscriptions, notifications, and admin dashboards included.

Based in Rohtak. Open to strong teams, hard problems, and work that ships.
